and now feel a new man!
Hi David,Please to hear you are feeling better Quote from: Stilldrillin on September 29, 2016, 01:22:40 PMand now feel a new man! Sometimes I think that I too would like to feel a new man but so far I have come to the conclusion that machine tools and castings sets are more reliable Jo
David, I don't see how the displacer can operate connected to the crank the way it is. Does the vertical bolt with the acorn nut on top slide up and down in the L shaped block on the crank, if so I would have thought there would be a lot of friction there. I would be trying to loose a good bit of weight on the displacer linkage. Also the displacer rod seems to be on the large side, but as long as the seal at the gland is OK, this should not cause any problem. The ratio between the displacer, and the power piston should be some where about 1.5 : 1, plus or minus a bit, a larger ratio will allow lower temperature. Minimum friction, no leaks, including the hollow displacer., and if it wont start remember that the displacer leads the power piston by 90*.Ian S C
